# Equation help! watch

1. I'm stuck!
x/2x-1 +2/x+2=1

I did this:
x(x+2)/(2x-1)(x+2) + 2(2x-1)/(2x-1)(x+2)=1
x^2+6x-2=1
x^2+6x-3=0
Now i don't know what to do. Let me know what I need to do please!

I'm stuck!
x/2x-1 +2/x+2=1

I did this:
x(x+2)/(2x-1)(x+2) + 2(2x-1)/(2x-1)(x+2)=1
x^2+6x-2=1
x^2+6x-3=0
Now i don't know what to do. Let me know what I need to do please!
Can you show how you worked out the quadratic equation from this
x(x+2)/(2x-1)(x+2) + 2(2x-1)/(2x-1)(x+2)=1.

I got a different quadratic equation.
3. Don't you know how to solve a quadratic?

The simplification is incorrect regardless.

I got a different quadratic equation.
x^2+2x/2x^2+3x-2 + 4x-2/2x^2+3x-2=1
x^2+6x-2=1
x^2+6x-3=0

I assume you mean ?
In which case I'm not sure how you got that simplification. I get:

From there expand the brackets and rearrange so the equation is equal to 0. Then solve like any other quadratic.

Thanks!

Thanks!
You got it?

You got it?
I think so.
X^2-3x=0
9. (Original post by isabel12144)
I think so.
X^2-3x=0
So x is 0 or 3?

If you've simplified correctly (I haven't checked your algebra!) those are the correct solutions to the quadratic equation you posted in your previous post

I think so.
X^2-3x=0
That is right
